This project involved designing and fabricating an assistive device. The client served by the device has a neurological disorder called dystonia that has rendered her arms and hands essentially useless for functional activities and has confined her to a wheelchair. The client uses her feet to perform daily tasks including writing and typing on a computer keyboard. To accommodate such activities, the client needs a work surface at her foot level. The goal of this project was to design a work surface that is both retractable and detachable from the user's powered wheelchair and can be operated independently by the user. The team designed and built a portable foot tray system that is attached to the undercarriage of the client's electric wheelchair. To date, the client has used the device at home, school, and physical and occupational therapy sessions. She is able to operate the device independently and it has proven to increase her self-reliance and functional independence.
